Need mastic sealing in Cote?
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Prioritise elevations facing the weather
- Make it easy for occupiers to report draughts
- Plan resealing building by building rather than complaint by complaint
- Check the asbestos register before any old mastic is disturbed
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
About our mastic sealing in Cote
For blocks and buildings in Cote and across West Sussex, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote, and site visits can be arranged. If you are dealing with a mix of products and colours from past repairs and water getting in round frames after rain, we can put it right. Looking for mastic applicators who cover Cote? We have been sealing commercial buildings since 2005.
Rural conversions near places like Cote often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Our workmanship is guaranteed for 12 months, in Cote as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What affects the price in Cote
We price every job individually. The main factors are:
- Location, for remote and island sites
- Induction, permit and paperwork requirements
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Details that help us quote
Whether it’s one area or a whole building, these details speed things up:
- Clear photographs of the problem areas
- Anything awkward about access or site hours
- Drawings or a marked-up plan, if available
- The type of building and who uses it
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Questions about Cote
Will you take on a block within reach of Durrington-On-Sea station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Does a coastal location like Cote affect which sealant is used?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Can you seal joints high up on a block?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Cote can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
What we need from you
- Tell us which areas need to stay in use
- Warn occupants and staff about the work
- Move anything stored against the joints

Mastic sealing in Cote: the local picture
Cote is within about 3 miles of the coast. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. Two care or nursing homes sit less than 2 miles from Cote. Owners of care premises can bring window and door mastic into a phased programme planned around the home.
Blocks of flats and mixed-use buildings often cluster around stations such as Durrington-On-Sea station, 1.8 miles south of Cote, and their window and balcony mastic tends to age at the same rate across a building. Site managers at schools like Durrington Junior School can fit frame mastic into the summer works. If you’re responsible for a building such as St Symphorian's Church, frame and door mastic needs the same attention as any other property.

When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Masonry that has broken away beside the joint
- Broken glass or failed sealed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If in doubt, phone 01277 525 020 or email drawings and photos and we’ll say what we think.
What we seal
- External wall and movement joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Balcony and threshold joints
What the job involves on each surface
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and keeps budgets predictable.
Also in Cote
Site staff or a sealant specialist?
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
